PROXIMITY Another very simple rule of perception is the tendency to perceive objects that are close to one another as part of the same grouping, a principle called proximity or "nearness." (See Figure 3.20.) SIMILARITY Similarity refers to the tendency to perceive things that look similar as being part of the same group. When members of a sports team wear uniforms that are all the same color, it allows people viewing the game to perceive them as one group ever when they are scattered around the field or court. CLOSURE Closure is the tendency to complete figures that are incomplete. A talentec artist can give the impression of an entire face with just a few cleverly placed strokes o pen or brush-the viewers fill in the details. The CONTINUITY The principle of continuity is easier to see than it is to explain in words. It refers to the tendency to perceive things as simply as possible with a continuous patterr rather than with a complex, broken-up pattern. Look at Figure 3.20 for an exam ple o continuity. Isn't it much easier to see the figure on the left as two wavy lines crossing each other than as the little sections in the diagrams to the right?
